启动postfix出错，查看centos中的postfix日志

more  /var/log/maillog

postfix: fatal: parameter inet_interfaces: no local interface found for ::1

vi  /etc/postfix/main.cf

发现配置为：

inet_interfaces = localhost

inet_protocols = all

改成：

inet_interfaces = all

inet_protocols = all

重新启动

service postfix start

OK！
